SHORT TERM
(TODAY)
ISSUED AT 251 AM CDT WED APR 2 2025
WARM, MOIST AIR CONTINUES TO ADVECT NORTHWARD INTO EASTERN
OKLAHOMA AND WESTERN ARKANSAS THIS MORNING THANKS IN PART TO GUSTY
SOUTHERLY WINDS NOTED ACROSS THE REGION. THE MAIN CONCERN IN THE
NEAR TERM IS THUNDERSTORM CHANCES, INCLUDING SEVERE POTENTIAL,
EVOLVING OVER THE NEXT FEW HOURS AND LASTING THROUGHOUT THE
MORNING HOURS. A COLD FRONT CURRENTLY DRAPED ACROSS NORTHWEST
OKLAHOMA WILL ADVANCE EASTWARD THROUGHOUT THE MORNING AND INTERACT
WITH THE WARM, MOIST AIRMASS IN PLACE WITH DEWPOINTS IN THE MID TO
UPPER 60S OVER MOST OF THE AREA. AT THE SAME TIME, AN UPPER LEVEL
JET STREAK ASSOCIATED WITH A SHORTWAVE TROUGH IS CURRENTLY
EJECTING OUT INTO THE PLAINS AS NOTED IN WATER VAPOR IMAGERY. HIGH
RES GUIDANCE CONTINUES TO INDICATE THAT STORMS WILL BREAK OUT
ALONG THE DRYLINE/COOL FRONT OVER THE NEXT HOUR OR TWO OVER
CENTRAL OKLAHOMA AS THIS SOURCE OF LIFT INTERSECTS THE
AFOREMENTIONED BOUNDARIES. THESE STORMS WOULD THEN ADVANCE
EASTWARD INTO EASTERN OKLAHOMA AND NEAR THE TULSA METRO AREA
AROUND RUSH HOUR THIS MORNING. UNCERTAINTIES STILL EXIST TO THE
EXTENT AND STRENGTH OF THESE STORMS AS A SUBSTANTIAL CAPPING
INVERSION IS STILL IN PLACE OVER THE REGION, THOUGH SLOWLY ERODING
AS LOW LEVEL MOISTURE INCREASES. STORMS MAY REMAIN ELEVATED IN
NATURE WHICH WOULD LIMIT THE TORNADO RISK SUBSTANTIALLY. STILL,
STEEP MID LEVEL LAPSE RATES AND STRONG DEEP LAYER SHEAR WOULD
SUPPORT LARGE TO VERY LARGE HAIL WITH ANY DISCRETE STORM. IF ANY
STORM CAN BECOME SURFACE BASED, THEN THE TORNADO THREAT WOULD
INCREASE AS WELL. STORMS WILL LIKELY BECOME MORE LINEAR AS THEY
ADVANCE EASTWARD, WITH THE SEVERE THREAT BEING MAINTAINED AS THE
LINE ADVANCES INTO A STILL HIGHLY UNSTABLE, HIGHLY SHEARED
ENVIRONMENT.
STORMS SHOULD CLEAR THE FORECAST AREA BY EARLY TO MID AFTERNOON AS
THE FRONT ADVANCES WELL INTO ARKANSAS BY THIS TIME FRAME. CLEARING
SKIES AND WARMING TEMPERATURES WILL FOLLOW INTO THE AFTERNOON
ACROSS EASTERN OKLAHOMA WITH BREEZY WESTERLY WINDS COMMON THROUGH
THE AFTERNOON.

LONG TERM
(TONIGHT THROUGH TUESDAY)
ISSUED AT 251 AM CDT WED APR 2 2025
ANOTHER ROUND OF SHOWERS AND THUNDERSTORMS IS EXPECTED TO DEVELOP
OVERNIGHT TONIGHT INTO THURSDAY AS A WARM FRONT LIFTS BACK NORTH
OF THE RED RIVER AND ANOTHER SHORTWAVE TROUGH MOVES THROUGH THE
SOUTHWESTERLY FLOW ALOFT. THE HIGHEST SEVERE CHANCES WILL STAY
CONFINED TO SOUTHEAST OKLAHOMA AND WEST CENTRAL ARKANSAS, SOUTH OF
THE BOUNDARY, WHERE LARGE HAIL WILL ONCE AGAIN BE A PRIMARY
THREAT. MORE ISOLATED THUNDERSTORMS AND SHOWERS ARE EXPECTED NORTH
OF THE BOUNDARY INTO NORTHEAST OKLAHOMA AND NORTHWEST ARKANSAS
THROUGH THURSDAY AFTERNOON.
THE CUTOFF UPPER TROUGH WILL BEGIN SLOWLY ADVANCING EASTWARD
THROUGH THE LATTER PART OF THE WEEK AND INTO THE WEEKEND, WITH
STRONG SOUTHWEST FLOW ALOFT CONTINUING OVER THE REGION THROUGH AT
LEAST SATURDAY. THE THREAT WILL TRANSITION TO MORE OF A HEAVY
RAIN AND FLOODING THREAT AS WE MOVE INTO THE WEEKEND, ESPECIALLY
ACROSS SOUTHEAST OKLAHOMA AND WEST CENTRAL ARKANSAS. SEVERAL
ROUNDS OF SHOWERS AND THUNDERSTORMS ARE EXPECTED FROM FRIDAY
THROUGH SUNDAY MORNING, FOCUSED ALONG THE STALLED FRONTAL BOUNDARY
MEANDERING OVER THE REGION. CONTINUED MOIST ADVECTION ALONG AND
SOUTH OF THE BOUNDARY WILL BRING UNSEASONABLY HIGH PWAT VALUES
INTO THE REGION FOR SEVERAL DAYS. EFFICIENT, HEAVY RAINFALL IS
EXPECTED NEAR THE BOUNDARY, WHERE UPWARDS OF 6-8 INCHES OF RAIN
COULD FALL LOCALLY BY THE TIME ALL IS SAID AND DONE ON SUNDAY.
FLOODING, BOTH FLASH FLOODING AND MAINSTEM RIVER FLOODING, WILL
LIKELY BECOME A CONCERN ACROSS A PORTION OF THE AREA. A FLOOD
WATCH WILL LIKELY BE NEEDED IN COMING SHIFTS AS GUIDANCE HONES IN
ON THE AREA MOST LIKELY TO SEE THE HEAVIEST RAINFALL.
THE TROUGH AXIS FINALLY SHIFTS EAST OF THE REGION DURING THE DAY
SUNDAY, WITH NOTABLY COLDER TEMPERATURES AND DRIER AIR FILTERING
IN BEHIND THE COLD FRONT FOR THE FIRST PART OF NEXT WEEK. LOW
TEMPERATURES BOTH MONDAY AND TUESDAY MORNING COULD APPROACH
FREEZING VALUES ACROSS THE NORTHERN HALF OF THE FORECAST AREA. THE
FORECAST LOOKS TO DRY OUT THROUGH AT LEAST THE FIRST HALF OF NEXT
WEEK, WITH PRIMARILY NORTHWEST FLOW ALOFT KEEPING TEMPERATURES
SLOW TO WARM THROUGH THE WEEK.

FEW HOURS. THE MOST COMMON IMPACT WILL BE STRONG GUSTY SOUTHERLY
WINDS OF 35-45 KTS FOR MOST AREAS, SHIFTING TO SOUTHWEST OR WEST
BEHIND THE STORMS, AS WELL AS VERY HEAVY RAIN. CEILING AND
VISIBILITY REDUCTIONS MAY ALSO BRIEFLY OCCUR WITH THESE STORMS.
SKIES WILL CLEAR LATER THIS MORNING AND AFTERNOON BUT CEILINGS
WILL REDEVELOP FROM SOUTH TO NORTH THURSDAY MORNING WITH SHOWERS
